The stainless steel precision casting process is different from traditional stamping processes. When designing the casting structure, it is necessary to fully consider whether the casting structure meets the requirements of the casting process. The rationality of the structural design of castings is related to the quality of casting pouring. A good structural design will reduce casting defects such as shrinkage, porosity, and deformation that occur during pouring. So, do you know what principles need to be paid attention to when choosing stainless steel precision casting methods?
The principles for selecting stainless steel precision casting methods are introduced as follows:
1. Priority should be given to sand casting, mainly due to its lower cost, simpler production process, and shorter production cycle compared to other casting methods.
2. The precision casting method for stainless steel should be suitable for the production batch. Low pressure casting, die casting, centrifugal casting and other casting methods are only suitable for mass production due to the high cost of equipment and molds.
3. The styling method should be suitable for the factory conditions. For example, when producing castings such as large machine tool beds, the core forming method is generally adopted, without making patterns or sand boxes, and the core is assembled in the pit; And another factory uses the sandbox molding method to make patterns.
4. The precision casting method of stainless steel should consider both the precision requirements and cost of the castings.
Strengthening ribs is an important structure in stainless steel precision casting. It can not only effectively improve the strength and stiffness of the structure, but also avoid the occurrence of large and thick wall components, reduce the use of materials, and improve the quality of castings.
